What are the causes of three -phase imbalances?There are many reasons that cause three -phase voltage imbalances, such as: single -phase ground ground, disconnected resonance, etc., can operate managers quickly deal with it can only be quickly distinguished.1. Dispel line failureIf a broken line but

High impedance transformers play an important role in limiting system short-circuit currents, and the issue of excitation inrush current has always been a major challenge in the application of high impedance transformers. Therefore, it is very important to effectively control the excitation inrush c

Main categoriesPlug in fuse: It is commonly used at the end of lines with voltage levels of 380V and below, as a short-circuit protection for distribution branches or electrical equipment.Spiral fuse: There is a fuse indicator on the upper end cover of the melt. Once the melt melts, the indicator wi
